An investigation committee formed by the Punjab government sealed a pharmaceutical factory which was manufacturing medicines allegedly responsible for the death of at least 28 people in Lahore. The Punjab government had formed a committee to probe the alleged reaction of cardiac medicines and consequent deaths of patients. Separate wards have also been formed in hospitals for the alleged victims of those medicines. Earlier, Dr. Prof Javed Akram, the head of the investigation team, said that the medicine may be contaminated with some heavy metal which gets deposited in the bone marrow and ultimately ends the body's resistance.
